Re: no sound or test tone from back surround speakers

Don't want to be an idiot, but what about mute? Maybe it's just me, but I was going crazy over a problem that turned out to be a balance knob turned sideways. Also do you have an A B speaker switch? could be that they're both depressed, or the wrong one is pressed. Was is it working when it happened? was there a pop? Check the fuse. Replace with correct fuse. Good luck

I have marantz Av surround receiver model SR301 I have tried a lot but I am having sound from only 2 speaker when I put in setero mode but when I put in surround no sound from any speakers I checked all...

First off you will need to do a little bit of trouble shooting. Is the source (dvd, Blu-ray, cable box, etc...) plugged into the receiver with the standard red and white RCA cord or by an optical (toslink-fiber optic) or digital RCA (orange color code). If you are connected with a standard RCA cord then that it your problem and you need buy digital cord that both the source device and the receiver can accept (toslink -,779.html or Digital RCA). If the connection is now correct then you need to make your receiver do a "test-tone" to insure that a signal can be sent to every speaker (this is an internal test that just checks the speaker connections). If the tone tone operates correctly then you know the amplifier is functioning. If both of the mentioned things are now done and still not surround output then you need to check the internal menus on your source device and make sure that it does not require you to manual change a setting in the audio menu to make it work (i.e. change from 2-ch 44KHz to 5.1 or 7.1 or Dolby Digital or AC3 or some other surround sound protocol.)

All 5 speakers work on test mode but on surround sound the left and right rear speakers are not working. How can this be?

Hello Ruby,

This is because your receiver is not in the correct surround sound mode for the number of channels being sent from the audio source, i.e. your TV or DVD player. It is likely your receiver is set for Dolby Digital (DD). You will need to switch your receiver to a Dolby Pro Logic (PL or PL II) setting to get audio from the rear speakers using your current audio source.

If you are unsure how to do this, please reply to me with the brand and model of the receiver. Some receivers have a "Surround Mode" button on the front of the unit or the remote. If you want to include further details of your setup, I can also give you some advice on attaining the best audio quality with the equipment you are using. You may be able to get Dolby Digital surround by changing some audio settings on the audio source or using a different connection.

Hope this helps. Please let me know if you need further assistance.

In dolby digital mode i can not get any voice volume. All other sounds are ok

Assuming that you mean Dolby digital 5.1, confirm that you have a center channel properly connected and perform the following;

Using the remote, enter the menu on the receiver and navigate to the selection labeled "LEVEL." Toggle through the selections until you reach the "CENTER CHANNEL". You will be able to use the remote to increase the volume of that channel in .5dB increments.

I'm going to surround sound mode, and my rear speakers are not working. I do a tone test, and they def work, but I can't get them working right?

Since you seem to be having problems with 'simulated' surround, how does ACTUAL surround material behave?

Have you tried AFD with certifiable multichannel source material to verify the surround speakers receive programmed sound??

Do the Dolby Digital or Pro Logic indicators light?

What about the other modes?

Right now my reciever will only play with two speakers (L and R). How do I get the 5.1 DTS back?

Are you using single digital coaxial or optical digital or the stereo RCA cable.
You might have that buttons on the remote for surround,2channel,3channel or 5.1 channel. orGo to the DVD's setup menu and click on "Audio Setup" or on "Languages" if there is no Audio Setup option and choose "Dolby Digital 5.1." (If you have a5.1, 6.1 or 7.1 system select "Dolby Digital EX" if it is an available option.) Depending on the age of the disc, the "Audio Setup" on the DVD menu may give you several choices: "5.1 Channel Surround Sound" or "Stereo Playback." If it's an old DVD, it might even say Dolby AC-3 (the professional designation for Dolby Digital 5.1). New DVDs may offer "Dolby Digital 5.1" and "Dolby Digital 2.0," the latter being stereo. Some of the disc menus offer only "Surround Sound" or "Stereo" options.

Did it ever work properly? If not, let's get down to basics and set it up for the simplest configuration it can have: FM source in stereo with front left and right speakers, no Surround Mode, no DSP, no Tape Monitor, no Mute, Volume not turned all the way down. Does that work?

Do you have Surround Speakers defined in System Setup A? If not, only Dolby Surround or Off are valid Surround Modes.

Is T2 Monitor indicator lit? Press the Tape-2 Monitor.
Is there acceptable sound other than during Speaker testing? NO? Is MUTE On?

Onkyo TX-SR500 Dolby Digital problem

I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1. According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected. Hope this helps.
